Iberis sempervirens


An evergreen sub-shrub which forms mounds of small, narrow, dark green foliage. From late spring it produces clusters of white flowers; the clusters are initially flat, then become more rounded.

What to use it for

Great for beds and borders, especially as edging and ground cover. Also works well in rock or gravel gardens, in wall crevices and in containers.

How to look after it

Requires little maintenance except the annual pruning described below.

Be careful not to overwater it.

How to prune it

Prune it lightly after flowering to keep it in a compact form. Can be hard pruned if it becomes too spread out.

Deadheading the first flush of flowers may also encourage a second flush later in the summer.

How to propagate it

Seeds can be collected in mid to late summer and sown in a cold frame in autumn. Alternatively, take semi-ripe stem cuttings in midsummer or use simple layering in spring or summer.

Common problems

Often munched on by slugs, snails and caterpillars. It is generally disease free.

This plant may spread invasively, particularly by layering wherever a stem touches the ground.
